Over the past year we have been developing a lens availability tool that imports data directly from lens manufacturers and summarizes the data into five categories, including PALs, multifocals, SF SV, and finished stock, to provide the most current (sometimes too current*) and complete picture of lens availability in one place.
*Manufacturers typically add lens data to their files before their release dates, so you may find a few lenses that are not actually available yet. We do not currently have a way to identify these lenses.
The database includes PAL identifiers within the details of each progressive lens as well as tool for matching identifiers to a particular lens.
We now have lens data for HOYA, AO, Sola, Zeiss, Younger, X-Cel, Essilor, Varilux, Signet Armorlite, Pentax, Seiko, and VisionEase.
You can access the tool here:

We are considering the application an alpha release, which is to say a very early version. We are still adding new features, data, and improving useabilty, so your feedback is important. Let me know what you think, particularly, if you have any suggestions, feature requests, bug reports, or would like us to add your lens data.
On the way:
Data cleanup and additions
Definity, Rodenstock, Tokai, and additional VX
Improvements to the PAL Identifier interface
Quick search filters for polarized, photochromic, and glass
Computer lens section
Hope you find it useful,
